Simple Benchmark Snippet

If you need to quickly benchmark some code in firefox (maybe chrome too) try the following function to make you life easier…

function benchmark(name, fn, n) { 
   console.time(name); 
   for(var i = 0; i < n; i++) 
      fn(); 
   console.timeEnd(name);  
}

…where name is an arbitrary test name, fn is the function you want to test, and n is the times to run the function.
